Specification of Letters Patent No. 9,606, dated March 8, 1853.

To all whom it may concern:

Be it known that l, SETH ADAMs, of Bos ton, in the county of Suffolk andState of Massachusetts, have invented new and useful Improvements inPrinting-Presses; and I do hereby declare the following is a full andexact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, in which Figure 1 is a longitudinal section on A B ofFig. 5. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4is a back elevat-ion. Fig. 5, is a plan. Fig. 6 a detached view of inkroller boxes, and upper part of ink roller frame. Fig. 7 is a detachedview of the ink roller frame.

The several parts of the press are designated by figures and letters,the same figures or letters referring to the same parts in each drawing.

In Fig. 1 the colored parts of the drawing indicate the parts cut in thesection.

35 is the fiy wheel attached to the driving shaft 39, to which shaft isattached pinion 29.

This pinion gives motion to the main spur wheel 28. This spur wheel isfixed on main shaft 40, to which two impression cams 15, 15, are fixed,also cam 16, for moving the inking rollers over the type.

22, is an arm on main shaft, through which and the bosses 22 22 runsbolt Q to connect the spur wheel and earns together, also for thepurpose of securing them firmly to main shaft.

33 is a grooved pulley fixed to the driving shaft, for the purpose ofdriving inking cylinder 2', which cylinder is driven by belt 34 andgrooved pulley 50.

44 is shaft of inking cylinder. On this cylinder is placed the vibratingink distributing roller 71., h, which is fixed on shaft 43, andsupported in its place, by the crooked stands or boxes u, u. Thevibration is given to this ink distributing roller, by the right andleft threaded screw 24 and tooth X.

23 is a weight to counterbalance the weight of the right and leftthreaded screw.

Z is the feed inking roller, which is supported in its place by thejournals at its ends being fitted to the ink levers W, W. These levershave a set screw A fitted into the ends of their arms at B. When theplaten 5 comes up it strikes against the set screws A, A, (there beingone screw in each lever) thereby moving the ink levers, which leverscarry the feed inking roller Z against the fountain roller X, where itreceives ink from the fountain y. When the platen b returns the leverslV, and feed inking roller Z follows it until the latter strikes againstthe ink cylinder 2', where it is held by spring 9., until it is movedagain by the platen b, for the purpose of communicating the ink it hasreceived from the fountain y, to the inking cylinder 2'. From cylinder2' the ink is taken to the ink rolls 9, 9. These rolls 9, g, are movedup and down over the type .9 and to the cylinder 5 by cam 16 by frictionroll 51 and lever 14, said lever being connected to the ink rollerframe-j by the link C. Said ink rollers are supported in their )laces bytheir journals being fitted to the ro ler boxes Z, Z.

70 is the case for roller boxes; m, springs to keep the rollers g gagainst the type and cylinder 2'; l), D, screws, on which are springs m,and boxes Z, Z. By turning said screws the ink rollers g 9 may be madeto press lighter or harder against the types 8 and cylinder 2' as may berequired. a, n are guides for the ink roller frame j.

49, 49, are stands for the fountain 2 y, is the fountain into which theink is put.

45 is the ink scraper; 46 screws, by turning which, the scraper isbrought nearer to or more distant from the fountain roll :0 as may berequired in order to give out the proper quantity of ink. The fountainroll m is turned a little by the pawls 21 taking into the ratchet 20 inthe fountain roller every time the feed inking roller Z is broughtagainst the fountain roll X.

52 is a grooved pulley fixed to the driving shaft 39, for the purpose ofcarrying the take off rollers. The band 53 leading from said pulley,turns roll f. Bands E, E, E, E, E, running from f to G, Gr, are to turnrolls G G and give direction to the paper into box K as it comes fromthe platen and passes between rollers G, Gr.

7 is a gage against which the paper is placed, for the purpose ofregistering it. This gage is put upon rod 42 and rests upon theplaten 1) during the time platen b is at rest, and while I) is going upto give the impression to the sheet; but when said platen returns to itsplace of rest, said gage is caught by the catch 10, and held suspendedtill the paper which has been printed on the platen b is carrieddownward by the motion of the tympan cloth to the two rolls G, G, whenit is taken between them and carried to the boX K. When the ink rollerframe 7' moves up, the projection R on cross bar 7" of said framestrikes catch 10 and disengages gage 7, when said gage is drawn down toits place on the platen b by spiral spring S, S. This operation is shownmore particularly in Fig. 8. it is again ready to receive a sheetagainst it to give it register this operation is shown more particularlyin Fig. Son the same sheet with Fig. 1. In order to carry the sheet downto the rolls G, G, the tympan cloth 30 on the platen is moved downwardas follows, viz: The tympan cloth 30 is connected to the segment a, bybelts. This segment is on shaft M. Vhen the impression has been givenand the platen b is returning to its place, catch 47 catches intoratchet 6, thus turning shaft M, and segment a, and giving motiondownward to the tympan cloth 30, which cloth carries the sheets with itto the take off rolls G, G, between which rolls the sheet is taken andconveyed to box K. I

48 is a spiral spring on shaft M, to bring tympan cloth back to itsplace. 0, is a gage against which to put the paper to register it. Thisgage is held to the platen b by screw L, and can be moved in the slot,to

conform to difierent sized sheets, by turning the screw L and thenmoving the gage as required.

1, 1, are two arms fitted to driving shaft 39. They make a frame to holdroll f and swing on their centers to hold bands E, E, E, E, tight. Thesearms are held down by spiral springs 41.

(Z, (Z, are two holders to hold the paper on the platen .7), while it isbeing printed, and to-draw it off the types after it is printed. Saidholders are on rod 42 and made movable so as to conform to any sizedsheet, by means of set screws in their ends, which are screwed against afiat place on the rod. In order that these holders shall not interferewit-h putting the sheet upon the platen b, they stand as represented indrawing Fig. 1, where they are kept by the arms 5 striking against stop6. WVhen the platen goes up, it strikes against these holders, andcarries them up with it. When the platen b returns, the said holdersfollow with it and are kept sufficiently hard against the platen to keepthe sheet in its place, by arm 1 on rod 12, and the spiral spring 3.

9, is the chase in which the type is locked. This chase is keyed to bed29 by key 2,.

s is type; the bed. The bed is screwed to the cross-piece 0, 0, 0, 0, byscrew 25. In order to adjust the bed and give more or less impression,four set screws, 26, 26, 26, 26,

lVh en are screwed into the cross-piece 0, 0, 0, 0, the ends of whichscrews set back against the bed. When these screws are turned theimpression is augmented or diminished as circumstances may require. Tokeep the bed firmly against the ends of these screws, spring 27 is putunder the head of screw 25.

38 is a table, on which to put the paper, it is screwed to each of thearms of the frame 31, 31, 31.

The platen I) has two arms in the ends of which are friction rollers 36,36. Said platen is hung on centers N, N. It is moved from its place ofrest, represented in Figs. 1 and 2, and brought up against the type andthe impression given, by the two cams 15, 15, on the main shaft.

18 is a treadle; 17, 17, connecting rods, which are attached to flywheel and pulley by crank pins 0, O, and to treadle at P.

37 is a spring to bring ink roller frame j back or down and keepfriction roller 51 against cam 16.

31 is the frame to which all the machinery is attached.

11 is a hand-lever, for stopping the impression of press. This lever hason it fork 12 which fits into the groove on clutch 13, said clutch isfitted to driving shaft 39, with a spline to prevent it from turning onsaid shaft. When this lever is moved to the right, it disengages clutch12 from a corresponding clutch on pinion 29 and leaves the pinion ondriving shaft, free or loose so that the spur gear and cams can stop.

Operation: This press is operated by first having the ink rollers 2, 2,h, h, i 2' covered with elastic composition in the usual manner, andthen putting them in their respective, places, for operation, asrepresented in drawing Fig. 1. Then put the ink into the fountain y, andadjust the fountain scraper 45, so as to let out a proper quantity ofink, by the set screws 46, 46; then place the blank paper on the table38, prepare the blankets and tympan cloth, on platen Z), and put on atympan sheet. Next put upon the platen, the sheet to be printed andadjust the sheet holders d, d, to the margin of the sheet, and the sizeof the form; also adjust the gages 0 and 7 to give the sheet register.This being done, adjust the impression by screws 26, 26, and thencommence printing by putting the fly wheel 35 in motion, by the treadle18. Thus the whole machine is put in operation, by the rotary motion ofthe fly wheel, which is fixed to the driving shaft 39, viz bycommunicating motion from pinion 29, which is on driving shaft 39 tospur wheel 28 which is on main shaft 40, and to which are fixed twoimpression cams 15, 15 thus giving these cams a rotary motion, theirsurface running against friction rolls 36, 36, which are in the arms ofthe platen b, and

causing by their rotary motion the platen to turn on its center N, N,and move up to the type and give the impression, and then recede back toits place, as represented in Figs. 1, and 2, where it rests about onethird of the revolution of the spur wheel 28, to give time to put onanother sheet, when it (the platen b) is moved up again as before; andby giving rotary motion to grooved pulley 33 on the driving shaft, andcommunicating the same to the inking cylinder i by the belt 34, whichalso gives motion to ink rolls h and 2, thus distributing the ink to betransferred to the ink rolls 6/, g, and from thence to the type, by thereciprocal motion of the ink roller frame j and by communicating rotarymotion to ink roller cam 16 on main shaft 40, said cam being shaped soas to move the ink roller frame j, containing the ink rolls 9, 9 up tothe inking cylinder 2' to receive the ink, where they remain till theimpression is given, and then are moved down, by the assistance of thespring 37, over the types to ink them, and back again to receive moreink, and by giving rotary motion to grooved pulley 52, on said drivingshaft, and communicating it by belts E, E, E, E to the rollers G, G, andby band 53 to the roller After the sheet has been printed, as beforestated, and when the platen Z) is going back, to its place of rest, toreceive another sheet, the catch 6%? takes into ratchet 0, which turnssegment a, and thus moves the tympan cloth, on which is the printedsheet, downward, and conveys it to the take off rolls G, G, betweenwhich it is taken and carried into boX K. Said tympan cloth is carriedback to its place of rest by spiral spring 48.

If by any mistake the sheet should be put on to the platen wrong, andthe press required to be stopped, to prevent the impression being given,or from any other cause the impression is required to be stopped, thisis done by moving lever 11 and disengaging c'lutch 12.

Having thus described my improvement in printing presses, I shall statemy claims as follows:

Vhat I claim as my invention and desire to have secured to me by LettersPatent 1s 1. The combination of said vibrating platenwith the sheetholders arranged as herein above specified, so as to be kept up a littledistance from the platen when in position to receive the sheetand movingwith said platen to the form,in order to hold the sheets thereon anddraw them from the types, also with the gages for registering thesheets.

2. I also claim the mode or means herein above described for keeping thesheet holders up from the platen when the sheet isto be placed, saidmeans consisting of an arm on each end of the rod (on which said holdersare fixed) and with which they turn, and stops against which said armsstrike, the arrangement and operation being substantially as hereinabove set forth.

3. I also claim the apparatus for delivering or taking off the sheetsfrom the platen after it is printed, consisting of the moving or slidingtympan cloth, in combination, with the turning segment at0 which anintermittent and reciprocating rotary motion is imparted by catch at?and ratchet e, and spiral spring d8, operating as above specified.
